Acetohalobium arabaticum (strainA TCC 49924 / DSM 5501 / Z-7288) is an obligate halophile, acetogenic, Gram-positive bacterium isolated from lagoons of the Arabat spit (East Crimea) which separates Sivash lake from the Sea of Azov. It produces acetate by reducing CO2. Growth is completely inhibited by 100 uM/ml streptomycin, benzylpenicillin, bacitracin, erythromycin, gentamycin, kanamycin, vancomycin or tetracyclin. It is an obligately anaerobe tolerating up to 12 mM H2S. Neither O2, S2O3 SO4, nor S0 can serve as electron acceptors. A. arabaticum requires a salt concentration of 10-25% NaCl and the optimum is 15-18% NaCl. The optimal pH is between 7.6 and 8.0. A. arabaticum exhibits three modes of nutrition: It is chemolithoautotrophic using H2 together with CO2 or CO; it is methylotrophic using trimethylamine (TMA); and it is organotrophic using betaine, lactate, pyruvate or histidine.
